Acne Therapy

Laser and light therapy. Laser- and light-based therapies reach the deeper layers of skin without harming the skin’s surface. Laser treatment is thought to damage the oil (sebaceous) glands, causing them to produce less oil. Light therapy targets the bacteria that cause acne inflammation. These therapies can also improve skin texture and lessen the appearance of scars. More research is needed to understand the most effective use of light and laser therapies in acne treatment, and experts currently recommend these approaches as stand-alone therapy only in people who can’t tolerate approved acne medications. These therapies may be uncomfortable and may cause temporary skin problems that mimic a severe sunburn.

Soft tissue fillers.
Collagen or fat can be injected under the skin and into scars to fill out or stretch the skin, making the scars less noticeable. Results from this acne scar treatment are temporary, so you need to repeat the injections periodically.

Dermabrasion.
Usually reserved for more severe scarring, dermabrasion involves removing the top layer of skin with a rapidly rotating wire brush. Surface scars may be completely removed, and deeper acne scars may appear less noticeable. Dermabrasion may cause pigmentation changes for people with darker skin.

Microdermabrasion. This newer acne scar treatment involves a hand-held device that blows crystals onto skin. These crystals gently abrade or “polish” the skin’s surface. Then, a vacuum tube removes the crystals and skin cells. Because just the surface cells are removed, the skin isn’t damaged. However, results are subtle and scars may still be noticeable, even after several sessions.

Laser, light source and radiofrequency treatments.In laser resurfacing, a laser beam destroys the outer layer of skin (epidermis) and heats the underlying skin (dermis). As the wound heals, new skin forms. Less intense lasers (nonablative lasers), pulsed light sources and radiofrequency devices don’t injure the epidermis. These treatments heat the dermis and cause new skin formation. After several treatments, acne scars may appear less noticeable. This means shorter recovery times, but treatment typically needs to be repeated more often and results are subtle.

Skin surgery.
A minor procedure (punch excision) cuts out individual acne scars. Stitches or a skin graft repairs the hole left at the scar site.
